Apex BI

Job Specification: Intermediate Full Stack Software Engineer

About Us

We’re a software company specialising in developing and deploying innovative solutions for ICT service providers and enterprise customers. We build products that simplify complex data and system integrations, enabling better visibility, cost management, and customer experience.

 

Our culture is built on flexibility, accountability, and speed. Our team is small, agile, and fully remote. This is an important aspect as you would need to be very comfortable in a remote first environment.

 

Even though we collaborate digitally, we have a tight-knit team. We make sure that new team members are on-boarded thoroughly during our personal, hands-on inductions which take place over several days. You’ll meet all the key people in the business and will spend time with all the stakeholders that your role will impact. Plus, we further support the development of working relationships through our informal, weekly, virtual water-cooler sessions on Friday mornings.
